WASHING-MACHINE.

Specii'ication of Letters Patent. Patntgd DEQ, `20, 1921 Application led July 28, 1920. Serial No. 399,509.

To all whom t may concern Be it known that we, EMANUEE B. ir/LER and JEROME ADLER, citizens ot the Unitedl States,- and residents oiiPittsburgh, in the county of Allegheny and State of lennsylvania, have invented a. new "and useful lmprovement in VVashing-h/laehines; and we Ado hereby declare the following to be a iull,

' which a suction cup o'r`inverted cone is reciprocated in the tub through the topf thereof. Each type of machine has points of merit not iound in the other. lt is the object of the present invention to combine' both types in a single machine, and to provide a machine. of the oscillating tub type within which is a reciprocable suction device.

A further object oic the invention is to combine the two types oi' machines into a single machine which will be compact 'and simple and have a comparatively simple operating mechanism. Y

A still further object of our invention is to provide a washing machine of this type having a tub adapted to eiiect a more vio#y lent agitation of the water without increasing the liability of injuring the clothes.

These and other objects will be apparent from the following description in connection with the accompanying drawings, in which,

Figure 1 is aside elevation oi a machineembodying our invention;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is' an .elevation ofthe end of the machine on which the wringeris mounted; and l Fig. i illustrates a section through the tub when ithas beenl oscillated in one direction to the limit of its movement. I Y

In the drawings, 5 indicates airame,pref erably madeo structural metal, supported on casters G. Supported on each side of the iframe at a point'approximately midwaybetweenthe ends, are bearings 7. Suspendedr within the frame by means ci trunnions 8 lsecured thereto, whichv are supported in bearn ings 7, is a substantiallysemi-circular tub 9, preferably having a corrugated bottom and corrugated sides. The trunnions 8 are prei'erably positioned eccentrcally on the tub, being 4below the center ofl lcurvature thereof. Spaced apart from each other in the bottoni of the tub area plurality, preferably three, deeper corrugations 10 which form relatively high ribs or ridges inside the tub. These ridges 10 serve to elle-ct a more violent agitation of the water and to move the clothes in the tub around more efficiently.

Each end 11 of the'top of the tub prei erably slopes toward a door 12 in the middle thereof, which is hinged at 13, the sloping portions forming draining' surfaces back into the tub; The door or cover 12 is formed with an inwardly projecting flange liladapted to form a substantially water tightcontact with the tub. On the back of the cover is a foot or lug 15 for engaging the top of the :trame 5 at 16, to permit the cover to be held substantially verticalwhen it is swung upwardly on hinge 13 to a vertical position. rl'his foot 15 also serves to prevent the tub trom reciting when the cover is open. On each side ot the cover 12, near the free end thereof, are shackles 17l adapted to be .engaged by sliding bolts 13 secured to the sloping top portions of the tub. These bolts serve to hold the Vdoor tightly closed when the machine is in operation.

Passing through a bushing 2O in the center ot the cover 12 is a rod 21 on the lowei1 end of which is a suction cup 22, or other suitable agitating device, which is preferably an inverted hollow element. rlhe upper end of therod is, provided with a roller 23 and surrounding the upper `portion of this rod is a compression spring 24 held in posi-- tion by a large washer Pivoted in a pair of ears or lugs 26 secured tothe cover is a curved lever or roc-lrv arm 27, the upper end of which is held in engagement with the roller 23 on the reciprocable rod21, andthe other end oi whichA is provided with a roller 23.` Fixed tothe frame 5 at 29 is a cam 30' operating lever 39. @n one part of the shaft there is a large Worm gear 40and a bevel gear 41. An electric motore-2 with a Worm gear 43 which engages Worm Wheel 4() serves to drive the shaft. The end of the divided shaft driven through the clutch 38 carries a crank 34. Gbviously, other forms of driving means than an electric motor could be employed fior driving the cranlr 44.

Secured to the bottom of the tub 9 is a pair oi lugs 45 to which is pivoted a connecting rod 46 having its opposite end pivoted to the crank 44.v 1t Will thereby be seen. that by f tending substantially the length of the trame and provided at one end with a bevel gear 57 engaging` bevel Wheel 44 on the divided sha it 37, and on the other end With a bevel Wheel 58. A vertical shaft 59 passesthrough the swivel support for the Wringer, and the lower end oi'this shaft is provided with a bevel Wheel 60 engaging the bevel Wheel 58. The

upper end of the shaft is provided With-a gear Wheel 61 which forms part of the re` versing clutch mechanism, the construction of which is known, and can be understood by l reference to the drawings.

A drain cock 63 is provided in the bottom of the tub for draining the Water therefrom.

In operation, the lid 12 is opened to vertical position, and the clothes or articles to be Washed are placed in the tub, together. with a suitable amount ot Water. The lid is then closed and bolted shut, after Which the-motor 42 -is started. By operating the lever 39 to shift the. clutch 38 into driving position, the crank 44 may be rotated to oscillatev the tub.

Such .oscillation of the tub Will cause the Water to move through and over the clothes and rub the clothes on the corrugated bottom and sides of the tub. By'reason ot the ridges 10 in the bottom of the tub, this action Will be more effective, the ridges serving to move the Water more violently. Y

The oscillation of the tub Will alsorcause the roller 28 on rock arm 27 to travel upan'd down the inclined surfaces of the cam30, rocking. the lever 27 and forcing rod 21 With the suction cup 22 downward against the compression of spring 24, thereby eiiecting the concomitant movement of the tub and-the reciprocable means.V By reason of the shape the clothes at a time When the Water beneath it is most shallow by reason of the tub being tiltedto the limit of its'movement.v Vhen the tub is horizontal, the cup is at its highest position, being returned thereto by the action of the compression spring 24. This mechanism also provides means for overcoming dead centers and avoiding unnecessary vibration when the tub reverses its motion.

Furthermore, by reason ot the cam havingy its lovvest position in alinement .With the trunni'ons, the action of the spring` 24 tends to cause the tub to stop in a horizontal position When the .clutch is thrown out oi driving position. After the clothes have been Washed, the-clutch is thrown out of driving position, the bolts released, and 'the lid or cover 12 opened. The Wringer 51 may then be operated by proper movement oi' lever. 55V
